Their observations include: • 401(k) plans have become too complicated for people to understand. They used to be explainable in a few minutes. There are now so many options and fees that people get confused.• People procrastinate thinking that they will always have time to save later.• People who do not get a 401(k) through an employer, often do not take advantage of their option to get individual retirement accounts.• The people who most need to save early, who are those with the least amount of income, are not the ones who are most incentivized by tax policy to use retirement accounts.
